The John Mollenhauer House, built in 1893, is significant under Criterion A for its association with the history of summer communities on the South Shore of Long Island at the end of the nineteenth and beginning of the twentieth centuries. Seeking an escape from the heat and bustle of New York City, successful businessmen and professionals built second homes, established social clubs, and developed the community of Bay Shore. John Mollenhauer, a German immigrant, started as a grocer and eventually founded several businesses, culminating in the Mollenhauer Sugar Refinery. Respected for his business acumen and success, he was known as the "Sugar King of Brooklyn." Dr. Raymond P. Sullivan, the house's second owner, rose to the top of his field in surgery. His success as a physician launched Sullivan and his family into New York's elite business and social circles. Sullivan and his family summered in Bay Shore for more than thirty years.
